Today, PTFE hydrophobic membrane has become a shining star in many industries. It has special properties that other materials do not have, giving it advantages that traditional materials do not have in many fields.
Membrane distillation is a typical hydrophobic membrane separation process and is considered a promising key technology for desalination and near-zero emissions.
However, the problem of hydrophilic leakage and drying of the hydrophobic membrane during the operation of membrane distillation is one of the key technical bottlenecks that prevents the practical application of membrane distillation technology in industry.
PTFE hydrophobic film, also known as PTFE bubble point film, is generally made of polytetrafluoroethylene suspended powder as raw material, which is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.1μm-0.5μm.
Generally, this film is laminated on various fabrics and substrates using special processes to become a new filter material.
PTFE hydrophobic membrane is a dense, smooth and porous film made by mechanical biaxial stretching using a special process.
PTFE bubble point membrane has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is covered with a special process Combined on various fabrics and substrates, it can become a new type of filter material. The membrane has small pore size, uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving advanced purification and Ventilation purpose.
